Ideal for navigating crowded city streets, this scooter is built for those who want the freedom of two-wheeled travel without the complexities of a larger motorcycle.

This lightweight powerhouse ensures that riders experience nimble handling and quick acceleration, perfect for darting through traffic or zooming around town.

Notably, the SF50B Prima is equipped with essential features that enhance rider comfort and safety. The front boasts a reliable single disc brake system, complemented by a drum brake in the rear, ensuring confident stopping power. The conventional telescopic front suspension and preload-adjustable mono shock absorber in the rear provide a smooth ride over uneven surfaces, making this scooter versatile in various urban environments. With an electric starter and a fuel capacity of 4.73 liters, the Prima is not only easy to start but also efficient, allowing riders to cover considerable distances without frequent refueling. **
